... Room Acoustics (Insert Room Acoustics Introduction Room Acoustics refers to how sound behaves in an enclosed space; more specifically, in a room. People have the general perception that the speakers in our stereo or home theatre systems are the final sound link in the whole sound chain. In other words, people believe that the speakers in the music system make the biggest difference to the sound that reaches our ears. But from a sound engineering point of view, the placement of speakers and the sound that proceeds from them in a stereo and home theatre setup is but partly responsible for what we hear. What many people do not know is that the room in which the sound has been set up determines to a...

... The Cool School (2008) and Visual Acoustics (2008) Many contemporary architects practicing in Los Angeles constitute a larger collection and rich legacy that dominated the 1950s, 60s and 70s from the local artists and post-war architecture scene. The Cool School (2008) and Visual Acoustics (2008) films help in understanding the key concepts of experimental architecture (or art). Experimental architecture is a fundamental functional art that employs the concept of space, which defines the boundaries of artwork and creates the limits of our lives. Architecture is more abstract and dependent on the concept of space. Moreover, experimental architecture adopts the concepts of utility and sound that form...

... New Empirical Model for Predicting the Sound Absorption of Polyfelt Fibrous Materials for Acoustical Applications I. Introduction Accurate modeling of the acoustical properties of porous materials is of considerable interest to acoustic and noise engineers and material manufacturers. Hence, there are many theoretical and empirical models which have been developed to predict the characteristic acoustic impedance and propagation coefficient of these materials. These models may be divided into three categories: empirical, phenomenological, and microstructural models. Empirical models do not require detailed knowledge of the internal structure of the material nor are they derived from theoretical...

... Vowel Acoustics A sinusoid, or a simple tone, can combine with numerous simplistic tones to create a complex tone, also known as vowel acoustics. In the 2003 study, Moore describes a sinusoid as a sine wave, the simplest sort of audible sound. A simple reaction of the human auditory system occurs as a direct result of sinusoids.
Sinusoids, which possess a “pure” sound, consist of three aspects. First, sinusoids are specified as possessing frequency, or the number of occasions per measured second in which a waveform completes one cycle by repeating itself, computed through hertz. One inclusive cycle of the waveform, or the time in which it takes to complete, is referred to as a period.
Another comp...

... Technical Music Analysis of Eleanor Rigby The song Eleanor Rigby opens up with verse (where refrain lyrically covers verse). The reason behind its opening with verse is because the chorus changes music change in the song along with eight bars.
Eleanor Rigby is a mixture of harmony and melody. The lead melody in the song is sounding Dorian mode which is relatively sharper than the degree of harmony in the song. The opening of the song is C-major. The reason behind this mixture of melody and harmony is that the composition has a consonant note. Metronome marking in the song is evident from the tempo. As per standard, Eleanor Rigby plays 120 beats per tempo. This is the reason behind considering the te...

... Models of Poroelastic Materials: A Review 3 Background The analysis, prediction and characterization of the acoustical behaviour and properties of poroelastic materials are of extreme importance in order to enable their appropriate utilization in various industries. Several models have thus been proposed to easily predict the acoustical behaviour of poroelastic materials. These models often use various physical parameters that are based on definitions from theory or measurements from experiments (Seppi 2009). However, the accurate prediction or characterization of poroelastics is still a difficult issue, especially in the case of numerical simulations of materials having complex geometries, due to...

... Walt Disney Concert Hall: An Analysis of Architectural Style Architecture is one of the milestones of culture. In Los Angeles, one of the main contributions of architecture to the modern era is the Walt Disney Concert Hall that has been constructed for 16 years. It has been opened in October 23, 2003 as the home of the Los Angeles Philharmonic (NAGATA Acoustics par. 1). A design of Frank O. Gehry, the landmark provides a state-of-the-art musical experience (Los Angeles Philharmonic Association par.1).

... Cathedral Built in the 12th and 13th centuries, Wells Cathedral is known for its soaring arches and unusual interior design. This cathedral is one of my favorites because there is always something to see that one didn't see before. The senses are nearly overwhelmed at times here and it is easy to forget one even has a body composed of anything but eyes and ears.
The site was founded as a church in about 705 A.D., and the beginning of the present cathedral originated under Bishop Reginald de Bohun, who died in 1191 (ed. David Nash Ford, 1924). The building of the present cathedral continued until 1239, under Bishop Jocelyn of Wells. The decoration of the West Front was completed in about 1260.
The e...

... Comparing Alberti’s St. Andrea with Vignola’s Gesu Renaissance Architects The plans of S. Andrea and Gesu share a striking resemblance. In both pieces of art, the chapels are arranged in a transverse manner. The barrels are vaulted. This is in contrast to the normal aisles that have columns. S. Andrea façade depicted the age of renaissance, where the lower roofs of the isles were linked to the higher naves using flanking scrolls. Central windows were much higher as compared to the windows of modern churches. The same design was employed in Gesu.
Their motives of using the plan were quite different. Alberti hoped to maintain the ancient Roman architecture of using decorations and monumental pieces o...

... s of learning and education have been a long-standing fixture in American history. The roots of the American education system back to before the colonies won their independence from Great Britain. Harvard College was founded in 1636, and shortly thereafter the College of William and Mary in Virginia (Hamby, 2005). The Massachusetts Bay Colony in 1647 enacted a law which required every village and town with more than 50 families to establish a grammar school, which mainly acted as a Latin school to prepare the young men and boys for college (Hamby, 2005). Though there were few actual schools in the Southern colonies due to the rural environment, tutors were provided for the children by wealthy...

... Don't Fret, Just Strum: A Comparison and Contrast of the Electric and Acoustic Guitar To an uninformed individual, all guitars are essentially the same, meaning they are all pieces of wood furnished with strings, which one plucks at or strums to make sounds. Most people are unaware that there are three primary guitar types, comprising of the electric guitar, classic guitar and acoustic guitar (Bacon 154). These guitars share remarkable resemblances despite being quite different both with regard to appearance and functionality. The acoustic and electric guitars are the most fascinating guitars. While these guitars have relative semblance in different areas, they are inherently different. The purpose...

... Wonders Full The telephone is perhaps the device that inspired technological advancements such as the computer, internet and cellular phones. Therefore, it can probably be fairly considered to be the most important invention in technology because it resulted to a lot of possibilities in the world of communication. It is known that the telephone was invented by the great Alexander Graham Bell, basing his work from his knowledge of acoustics and electricity (Farley, 2006). This combination of ideas is believed to be what made the Scottish scientist succeed in his endeavor. Today, many people benefit from the said device, making communication easier especially for families who need to be away from each ...

... Introduction Reverberant conditions can be either simulated or natural. Simulated reverberant conditions tend to be diotic, which means that they produce one sound for each ear simultaneously. On the other hand, real reverberation tends to be diffuse, which is the result of multiple sounds bouncing off of irregular walls, such as can be found in concert halls. It has traditionally been difficult for simulations to duplicate the reverberation found in natural environments, which is a limitation to simulated reverberation. However, at least one researcher has found a way around this, as he has created a simulated environment that can be used in natural reverberant environments that are marked by...
